MOTOR-TRUCK.
Specification of Letters Patent.
Application filed June 4., 1914. Serial No. 843,045.
To all whom it may concern Be it known that I, HADWEN SWAIN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Tmprovements in Motor-Trucks, of which the following is a specification.
My invention relates to an electrically driven truck on which the electrical power is generated by means of' a generator operated by a gas engine or other suitable power and the energy stored in a battery and then utilized through a motor to drive one or more wheels as desired, and the object thereof is to provide simple and eflici'ent mechanism for that purpose in which the side pressure or friction on the axles is largely relieved by means of a balanced drive. 7
In the drawings forming a part of this application, Figure l is a side elevation of my improved truck. Fig. 2 is a top plan with a part of the platform removed. Fig. 3 is an enlarged side elevation of the driving mechanism of the rear wheels with --a part of the casing or covering removed. Fig. 4 is a section on the line H of Fig. 3.
h Fig. 5 is an enlarged side elevation of the driving mechanism of the front wheels with parts of the casing removed. Fig. 6. is a section on the line ti -6 of Fig. 5, with parts in elevation.
Tn the drawings my truck is shown as a l truck with a low hung body and l will describe it as such but the truck may be built with a medium or high hung body. In the latter case the spring suspension of the body tion would not be changed.
and the shape of the axles would be differ-' ent but the essential features of'the inven- The frame of the body of the sists of the longitudinal members 10 which run the entire. length of the'body, ind 11 t the side members areconnected by transverse members 12. The members of the frame 3 are preferably constructed of til-shaped channel iron but any suitable shape may be ,1 lit) it is lighter for any given strengththan any used. T prefer the U shaped channel'iron as shape that T know of. Upon the top of the frame is secured a floor or platform 14. Tn

angles to the straight portions and are vertical when positioned for use and pass downwardly just within the side members 10 of the body and to a point below the floor. The central portion passes transversely below the floor. In a high hung body the axle would be straight and pass transversely below the frame. Secured upon the axles, above the side members'in a low truck, are suspension springs of which there are preferably two springs for each wheel. These are placed in a more or less parallel position. The springs for each wheel may be one above the other as shown in the drawing or side by side as preferred. tlne of them, which is shown in the drawmg as the upper one at 17 is lighter than the other 16 which may be shorter if desired. llf placed one above the other they are spaced by the block 18. The drawing shows the upper or lighter springs having pivotally secured links 19, which are connected to eye bolts 20, mounted on the outside members of the frame. At the ends of the lower springs are placed one above the other, than links 19. The links 21 are connected to eyebolts 22 mounted in the outer members of the frame. The eyes of eyebolts 22 are the eyes of eyebolts 20, or the holes in the ends of springs 16 are lengthened vertically, so that the frame, before any load is placed thereon, is hung suspend. ed from the lighter springs. As the body is being loaded, as soon as the weight of the load flexes the lighter springs to a certain extent the heavier. springs are brought into play and the body and load are suspended by both the lighter and heavier springs. When the truck is being driven by two wheels the power may be applied to either the front or back wheels. "It will be un derstood that each wheel is being driven separately from the other Wheels.
Onthe'rear axles are mounted wheels 25g of sultableeonstruction for truck service.
The inner hubs of therear wheels 25 are flanged at '27 and bolted to 25 by bolts 28. These hubs are extended inward through 26 in a tubular form to 31, the latter surround but do not touch the bearing 29 of the case 30. This bearing 29 is supported by the axle 15. lii has its outer ends straight and horizon- Placed around outside of the hub31 is the universal ring 33,'this ring has oppo-' sitely disposed, two projections 32 which go into two suitable recesses 31 in the outer surface of hub 31. The universal ring 33 is a loose fit in the wheel hub 31 so the jar of the road will not affect the gears, etc. These universal rings 33 are placed inside of the worm gears 34 and engage the latter through two oppositely disposed projections 36 spaced equidistant from pro ections 32 on the outer surface of the universals 33, and projecting into suitable recesses 35 in the worm gears 34, the universals not fitting tight, so as to allow some play.
The various devices are alike in both rear wheels. Lugs 32 and 36 are narrower than the recesses into which they are received so as to'allow a slight play for starting.
tion.
which there are any suitable number, to a driving plate 68 which is bolted to the front wheel. Pins 67 are received in recesses 69 in driving plate 68. These recesses are a little longer than the diameter of the pins to allow of a little reactive motion when the wheel runs into a rut or over an obstruction. The steering mechanism is of the usual automobile type and is not further shown or described as a part of my inven- It will be understood that suitable control switches are used whereby one or more motors can have its supply of current regulated or cut off entirely independently of the other motors.
In the drawings I have shown each wheel driven by two worms as they balance the drive, and I prefer that construction, but a single worm may be used, or other gears than worms may be used.
If desired the front wheels may be driven by bevel gears instead of the worms shown. One gear is concentric with the knuckle pin 55.
Having described my invention what I claim is 1. In an electrically driven vehicle in combination a motor; a shaft driven thereby; a worm on said shaft; a worm gear engaged by the worm; a driven wheel; a connection between said driven wheel and said worm gear; a second shaft operatively connected to and operated by said first shaft; and a worm on said second shaft operatively engaging said worm gear and oppositely disposed as to the first worm.
2. In a ,vehicle, a. running gear comprising wheels and front and rear axles; a. body; a spring connection between said body and running gear; cases pivotally mounted on the rear axle and pivotally connected to the body, one on each side, said cases forming radius or distance rods; and independent driving means for each rear wheel mounted on said radius rods.
3. In a vehicle, front and rear axles and wheels mounted thereon; a spring supported body; cases having one end pivotally mounted on the rear axle and the other end pivotally connected to the body, said cases forming radius rods, there being a case on each side of the body; and means to drive the rear wheels thereof mounted on said radius rods, each wheel being driven independently of the other wheel.
4. In a vehicle having a spring supported body and two independently driven rear wheels, a case pivotally mounted on the rear axle at one end and pivotally connected at the other end to the body, said case forming a distance or radius rod and being adapted to receive and support the driving mechanism of a rear wheel.
5. In an electric vehicle a driving and a driven ring; and an intermediate ring opmomee eratively but 10ose1y engaged by both the driving and driven ring forming a par tween the driven 5 mechanism whereby on the driven Wheel being transmitted to rings, said intermediate t of the connection be- Wheel and the driving portions of the shock Will be prevented from the driving mechanism.
